== Why is this an issue?

include::../description.adoc[]

Using the regular expression ``++^[a-z][a-zA-Z0-9]*$++``, the noncompliant code below:

[source,php,diff-id=1,diff-type=noncompliant]
----
class MyClass {
  $my_field;
}
----

Should be replaced with:

[source,php,diff-id=1,diff-type=compliant]
----
class MyClass {
  $myField;
}
----
